15 n^{2} - n - 2 = 0

n = \frac{2}{5}, n = - \frac{1}{3}

Decimal Notation

n = 0.4, n = - 0.33333 \dots

Solution steps

15 n^{2} - n - 2 = 0

Solve with the quadratic formula

n_{1, 2} = \frac{- ( - 1 ) \pm ( - 1 ) ^{2} - 4 \cdot 15 ( - 2 )}{2 \cdot 15}

(- 1)^{2} - 4 \cdot 15 (- 2) = 11

n_{1, 2} = \frac{- ( - 1 ) \pm 11}{2 \cdot 15}

Separate the solutions

n_{1} = \frac{- ( - 1 ) + 11}{2 \cdot 15}, n_{2} = \frac{- ( - 1 ) - 11}{2 \cdot 15}

n = \frac{- ( - 1 ) + 11}{2 \cdot 15} : \frac{2}{5}

n = \frac{- ( - 1 ) - 11}{2 \cdot 15} : - \frac{1}{3}

The solutions to the quadratic equation are:

n = \frac{2}{5}, n = - \frac{1}{3}

5 x - 4 x^{2} = 0

x^{2} y^{2} + x^{2} + y^{2} + 1

6 = n^{2} + 3 n - 12

- \frac{6}{9}

0 - y = 5
